Answer:
93
Step-by-step explanation:
15 x 5 = 75 + 18 = 93
Answer:
That is a infinite solutions equation, but to solve this you would have to subtract 3x from both sides and you will get 4=4.
Step-by-step explanation:
3x+4=3x+4
<u>-3x -3x</u>
4=4
They are not like terms. So false.
5x^2y is not the same as 7xy^2 because the exponent is on different variables.

The ratio of the wavelengths of the two notes is 2:1 option fourth 2 to 1 is correct.
<h3>What is wavelength?</h3>
The wavelength is the distance between two successive troughs or crests. The highest point on the wave is the crest, while the lowest point is the trough.
We have two notes
Number of cycle for blue = 8
Number of cycle for red = 4
Ratio = 8:4 = 2:1
Or
2 to 1
Thus, the ratio of the wavelengths of the two notes is 2:1 option fourth 2 to 1 is correct.

<u>Answer:</u>
x = 14° || each angle has 108°
<u>explanation:</u>
first we need to find the total interior angle of this shape:
formula: ( n - 2 ) * 180 ..............where n is the number of sides
( 5 -2 ) * 180
540°
if all sides in the shape are equal, they must have same angle of 9x -18
5 ( 9x -18 ) = 540°
9x -18° = 108°
9x = 108° + 18°
9x = 126°
x = 14°
So each angle has: 9x - 18
9(14) - 18
108°
